How to check the oil level in my Audi A4?

I just bought a used Audi A4 and I want to make sure that the oil level is at the right point before I start driving it. Can you give me some tips on how to check it?

First, make sure the car is on a level surface and the engine is turned off. Then locate the dipstick, which is usually labeled with a bright yellow handle. Pull it out and wipe it clean with a paper towel. Then re-insert the dipstick and pull it out again to get an accurate reading.

After pulling out the dipstick, look at the two marks on the end of it. One will indicate the minimum level and the other will indicate the maximum. The oil level should fall between these two marks. If it is below the minimum, you'll need to add more oil.
